Description

Technical Field

[0001] The present invention belongs to the technical field of bag pile sleeves, and more specifically, relates to an automatic bag pile installation system and a construction method thereof. Background Art

[0002] Outer bag concrete bored piles (commonly known as "bag piles") are an important new technology and new achievement applied in pile foundation engineering in corrosive areas and karst cave areas. Developed on the basis of the original concrete bored piles, the structure includes a concrete pile body with a steel cage inside. The outer surface is wrapped with a two-cloth and one-film composite geotextile bag material with excellent waterproof and anti-corrosion properties to isolate corrosive substances from penetrating into the pile body and prevent concrete from flowing into the karst cave. The composite geotextile bag is made by hot pressing or welding two layers of polyethylene geotextile bags with a layer of geomembrane in between. The construction method is to put the steel cage with the bag after the hole is completed and accepted, and then lower it into the pile hole, and then lower the guide tube to pour the concrete.

[0003] In the prior art, bag-filled pile installation typically involves a crane hoisting the rebar cage, followed by construction workers slowly applying the bag over it. This process is not only labor-intensive but also prone to worker fatigue, increasing the risk of operational errors. In complex geological conditions, such as those found in corrosive and karst regions, the construction environment is harsh. Workers working in such conditions for extended periods of time is not only labor-intensive but can also adversely affect their health. Furthermore, bag installation requires manual crane operation, making the installation process complex and time-consuming, significantly impacting the overall progress of the pile foundation project. This efficiency issue can lead to delays and increased construction costs, particularly in large-scale projects. During the manual installation process, the bag is easily damaged by friction, collisions, and other factors, compromising its waterproof and anti-corrosion properties. For example, workers may accidentally scratch the bag while applying it, causing it to lose its protective properties. Precisely controlling the bag's installation position can lead to problems such as loose fit between the bag and the rebar cage and wrinkles, compromising the overall performance and service life of the bag-filled pile. Consequently, the installation of bag-filled piles in the prior art is time-consuming and difficult.

[0004] Although there are some improvement measures in the existing technology, there are still limitations: some adopt a folding steel frame, and the bottom end of the bag adopts an enlarged head type. After the bag is lowered and poured, it pulls the steel frame to expand to form a reinforced concrete bag pile. Although it can solve the problems of difficulty in pile formation in lava areas and poor stability after pile formation, it is only applicable to folding steel cages, not to conventional steel cages. It cannot solve the problems of high difficulty in installing bags for conventional steel cages and long installation time. Some also use a variable-section steel frame bag pile structure, including a steel cage, a grouting pipe inserted into the steel cage, and a bag sleeved outside the steel cage. The steel cage is provided with an auxiliary support structure. Although it can solve the technical problem that the existing bag pile structure is unstable during construction, resulting in the bag shaking during the cement slurry pouring process and thus the instability of the bag pile structure, it is only applicable to variable-section steel cages, not to conventional steel cages. It cannot solve the problems of high difficulty in installing bags for conventional steel cages and long installation time. Others use a number of supporting longitudinal bars and connecting longitudinal bars to form a steel cage. The top and bottom outer sides of the steel cage are both provided with annular fixed stirrups for fixation. A telescopic deformation control device and a number of deformable stirrups are provided inside the steel cage. The telescopic deformation control device is connected to the deformable stirrups to achieve the purpose of changing the cross-section of the steel skeleton. However, it is also only applicable to variable-section steel cages and cannot be applied to conventional steel cages. It cannot solve the problem of the high difficulty and long installation time of conventional steel cage bags. The existing technology lacks versatility and cannot adapt to steel cages and bags of different lengths and specifications. As a result, in actual applications, multiple adjustments and improvements are required for different construction scenarios, which increases the complexity and cost of construction.

[0005] In summary, the existing technology has many defects in construction efficiency, labor intensity, installation accuracy, scope of application, construction quality and safety risks. Summary of the Invention

[0034] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0035] (1) The system and method for the automated bag installation of bag piles of the present invention are characterized by providing a lifting mechanism at both ends and connecting them through a connecting rod assembly. The connecting rod assembly passes through the center of the steel cage and the bag to lift the steel cage and the bag to a certain height. The system and method can solve the problem that in the traditional installation process, the rope will hinder the smooth installation of the bag when the crane lifts the steel cage, thereby realizing the convenient installation of the steel cage bag, significantly improving the installation efficiency, reducing the installation difficulty, and bringing great convenience to the construction of bag piles.

[0036] (2) The automated bag-sack installation system and construction method of the present invention achieves the simultaneous lifting and automated installation of the steel cage and bag through the coordinated operation of the steel cage lifting mechanism and the bag traction mechanism. Compared with the prior art method of installing the bag by manual labor and crane, the automated system of the present invention greatly reduces the complexity and time consumption of manual operation. Through the precise control of the traction control device, the installation process of the steel cage and bag is more efficient, and the installation time can be shortened by more than 50%, which significantly improves the construction progress, especially in large-scale pile foundation projects.

[0037] (3) In the prior art, the installation of bags usually requires a large amount of manpower in conjunction with crane operation, which is labor-intensive and inefficient. The bag pile automated bag installation system and construction method of the present invention, through automated equipment and control devices, reduces manual intervention and labor intensity, while avoiding possible mistakes and safety hazards that may occur in manual operation. The use of the automated system not only improves the safety and comfort of construction, but also reduces the risk of construction accidents caused by human factors, further improving the overall safety of the construction site.

[0038] (4) The bag pile automatic installation system and construction method of the present invention integrates multiple sensors (such as position sensors, force sensors and angle sensors) to monitor the lifting height, traction force and installation position of the steel cage and bag in real time, ensuring the accuracy and stability of the installation process. Through the automated traction and control device, friction and damage to the bag during the installation process are avoided, ensuring the integrity and waterproof and anti-corrosion performance of the bag. In addition, through the optimized bag traction mechanism and traction control device, the bag can be accurately installed outside the steel cage, improving the installation accuracy and construction quality, extending the service life of the bag pile, and providing a guarantee for the long-term stability of the pile foundation project.

In the bag pulling mechanism 2, the traction rope 24 of the winch 21 is equipped with a position sensor and a force sensor. The position sensor monitors the pulling position of the bag, while the force sensor monitors the pulling force. A force sensor is installed between the jacks 112 and the connecting disc 113 to monitor the lifting force of the jacks.

[0061] like Figure 6 As shown, the second aspect of the present invention provides a bag pile automatic installation method, comprising the following steps:

[0062] S1: Arrangement of the rebar cage lifting mechanism 1 and the cloth bag traction mechanism 2: Place the rebar cage 4 and the cloth bag 5 in a straight line on a flat and solid ground, ensuring that the center line of the rebar cage and the cloth bag is parallel to the ground; place a first hoist 11 at the end of the rebar cage 4 away from the cloth bag 5, and place a second hoist 12 at the end of the cloth bag 5 away from the rebar cage 4; place a winch 21 on top of the first hoist 11; install a ring 22 on the cloth bag 5 near the end of the rebar cage 4 and secure it; install balls 23 with sockets on the end of the rebar of the rebar cage 4 near the end of the cloth bag 5; the balls should be evenly distributed at the edge of the end of the rebar cage;

[0063] S2: Connecting the connecting rod assembly 13: Determine the number of intermediate connecting rods 132 according to the length of the steel cage 4 and the cloth bag 5; assemble the intermediate connecting rods 132 and the end connecting rods 131 using a screw and a sleeve; pass the assembled connecting rod assembly through the center of the steel cage 4 and the cloth bag 5, and plug the end connecting rods 131 at both ends into the connecting disc 113 of the hoist, ensuring that the plug is tight and not loose; connect the ring 22 on the cloth bag 5 to the hoist 21 via the traction rope 24; the traction rope 24 should be taut, but not excessively stressed;

[0064] S3: Sensor installation and debugging: Install a displacement sensor on the top of the jack 112 or on the connecting disc 113 to monitor the lifting height of the steel cage; install a position sensor and a force sensor on the traction rope 24 of the hoist 21 to monitor the traction position and traction force of the cloth bag; install a force sensor between the jack 112 and the connecting disc 113 to monitor the lifting force of the jack; install an angle sensor on the top of the jack 112 or on the connecting disc 113 to monitor the tilt angle of the steel cage 4 and the cloth bag 5 during the installation process; debug each sensor to ensure that it can accurately collect data and transmit it to the traction control device 3;

[0065] S4: Lifting and traction: Connect the first hoist 11, the second hoist 12, and the winch 21 to the traction control device 3 respectively; extend the jacks 112 in the two hoists through the traction control device 3, drive the connecting rod assembly 13 to rise upward, and lift the steel cage 4 and the cloth bag 5 to a certain height from the ground; during the lifting process, the traction control device adjusts the extension and retraction speed and torque of the jacks in real time according to the feedback signals of the displacement sensor and the angle sensor to ensure that the steel cage and the cloth bag are lifted smoothly and the steel cage remains horizontal; retract the traction rope 24 of the winch 21 through the traction control device 3, and then pull the cloth bag 5 to slide along the outer surface of the steel cage 4 away from the end where the cloth bag 5 is located; during the traction process, the traction control device 3 adjusts the traction speed and torque of the winch 21 in real time according to the feedback signals of the position sensor and the force sensor to ensure that the cloth bag 5 can be smoothly and evenly covered on the steel cage 4, and the traction force is moderate to avoid damage to the cloth bag 5; when the cloth bag 5 completely covers the steel cage 4, the traction control device 3 automatically controls the winch to stop working;

[0066] S5: Equipment disassembly and transfer: Untie the traction rope 24 between the ring 22 installed on the bag 5 and the hoist 21, shorten the jacks 112 in the hoists at both ends to the minimum through the traction control device 3, and place the steel cage 4 with the bag 5 installed on the ground; move the connecting rod assembly 13 to the left or right to disconnect it from the hoist and pull it out of the steel cage; move the equipment to the next steel cage 4 and bag 5;

[0067] S6: Repeat steps S1-S5 to continue installing the cloth bag 5 on the steel cage 4.

[0068] Furthermore, step S5 includes post-installation inspections, such as a visual inspection to ensure that the bag completely covers the rebar cage, that the surface is flat, wrinkle-free, and undamaged, and that the bag fits snugly against the cage. Quality testing: Non-destructive testing methods are used to inspect the bagged piles to ensure that the bag's waterproof and corrosion resistance meets requirements and that the cage structure is intact. Site cleanup: The construction site is cleaned, and any remaining materials and equipment are properly stored to ensure a clean and safe construction site.

[0069] The automated bag installation system and construction method for bag piles provided by the present invention utilizes lifting mechanisms at both ends connected by connecting rods. The connecting rods pass through the center of the rebar cage and bag, raising the cage and bag to a certain height. This solves the problem of ropes obstructing bag installation when the rebar cage is lifted by a crane, thereby facilitating the installation of the rebar cage bag. A bag traction mechanism is provided, and the rope is retracted via a winch, allowing the bag to be quickly pulled from the other end to one end of the rebar cage. This solves the problem of workers having to coordinate with the crane to install the bag, significantly shortening the installation time of the rebar cage bag. A circular ring is installed and secured at one end of the bag near the rebar cage, and a round ball with a socket is installed at the end of the rebar near the bag end. This solves the problems of the bag colliding with the rebar during installation, damaging the bag, and preventing the bag from passing smoothly through the rebar cage. This reduces costs and speeds up the installation of the rebar cage bag. The coordinated operation of the lifting mechanism, bag pulling mechanism, and traction control device enables the simultaneous lifting and automated installation of the rebar cage and bag. This solves the problem of low worker efficiency in installing the bag on the rebar cage, achieving high-speed and efficient automated installation of the rebar cage bag. The automated equipment and control device significantly reduce manual intervention and labor intensity. The use of the automated system not only improves construction safety and comfort but also reduces the risk of construction accidents caused by human error. By installing displacement and angle sensors on the top of the jack and the connecting disc, the system monitors the lifting height and tilt angle of the rebar cage in real time, ensuring a smooth and accurate lifting process. During the bag pulling process, by installing position and force sensors on the winch's traction rope, the system monitors the bag's pulling position and pulling force in real time, preventing damage to the bag due to uneven force during the pulling process. These automated control measures not only improve installation efficiency but also ensure the safety and reliability of the construction process, further enhancing overall construction site safety.
